摘　　要：分析了蝶式止回阀在实际生产中常见的故障及损伤状况,利用有限元模拟软件对原始的蝶式止回阀结构进行模拟分析验证,针对薄弱部位进行结构改进,对改进后的止回阀阀瓣进行应力和形变分析,设计出受力分布均匀、变形量小的结构形式,提出故障解决方案。The butterfly check valve is analyzed in the common faults and damaged conditions in the process of production,by using finite element simulation software for simulating the original butterfly check valve structure analysis,given the weak parts of structure improvement,for the improved check valve disc on stress and deformation analysis,design the structure of uniform stress distribution,deformation small,puts forward solutions to the fault.
